Did you know that in 2024 members the AmericaView Education and Outreach Team put together a series of lessons explaining how remote sensing and Earth observation technologies are integral to various sectors within society? These lessons are great! They are geared for middle and high school but can be adapted for your classroom. All six lessons follow a similar pattern: introduction, standards, warm-up (What’s going on in this picture?), a reading exercise, an online map exploration, a career exploration related to the topic, a quiz/assessment, and an online/printable game.
Over the next few months, we will be taking time on the blog to dig into these lessons. We hope you enjoy unpacking these lessons and learn more about earth observation and remote sensing. If you have any questions or suggestions for new lessons, feel free to email IowaView Coordinator, Amy Logan or leave a comment.
Earlier this year, IowaView Staff member, Amy Logan, created a new piece of art for IowaView’s Iowa as Art Collection. The piece is called Cautionary Waters. It is based off an IowaView blog post, Change Over Time – Flooding on the Landscape (NW Iowa), a series of IowaShots images that were released in 2022. This piece revisits those images and includes new Landsat images from the 2023 drought and 2024 flood.
Cautionary Waters: Visons of the Past, Planning for the Future
How are we planning for the future in our communities? Cautionary Waters is a piece of artwork that asks us to think about this question.
The piece includes four Landsat satellite images of the same area of Northwest Iowa taken in 1990 (a normal year, upper left), 1993 (a year of memorable flooding in the Midwest, upper right), 2023 (a year of drought, lower left), and 2024 (another year of memorable flooding, lower right). White areas in these images are water. These two flood events were roughly 30 years apart.
The piece asks viewers to reflect: when we are planning, do we consider only typical conditions, or does our planning account for extremes, flood or drought as well? Are we willing to allow development in the floodplain and take the loss when the flood comes, or perhaps make a harder choice to not develop there and lose out in the short-term? Also, in cases when we choose to develop in lower elevation areas, what kinds of zoning and development are we allowing in these areas?
The piece is currently on display as part of the “Do Justice” art exhibit at Harvest Vineyard Church, in Ames, Iowa, which runs through the end of January 2025. After that the piece is available for loan on a first come, first serve basis. If interested in displaying the piece or other Iowa as Art pieces, please contact, Amy Logan, IowaView State Coordinator for additional details.

Earth Observation Day 2024 is finally here as it the release of the AmericaView 2024 Earth Observation Day Poster! The poster is following the theme of this year’s Earth Science Week theme, “Earth Science Everywhere”. The front of the AmericaView 2024 Earth Observation Day poster features 6 image themes: agriculture, disaster, forestry, urban land use, water, and wildlife. The back of the poster explains the significance of the images and provides links to 6 themed lesson plans. IowaView was responsible for the disaster management lesson plan.
The ISU GIS Facility will be hosting the 3rd annual geospatial summer workshop for K-12 teachers and pre-service teachers in Ames, Iowa on July 17 – 18, 2024. This workshop will show many geospatial tools and applications from the Esri ecosystem as well as Google Earth, OpenStreetMap, AmericaView, and others. Teachers will get to see a variety of map tools and exercises that they can bring into current lessons. We will explore resources available at local, state, and national levels. Each participant will make a StoryMap to use in their classroom. Teachers can sign up for graduate or continuing education credit. Please email Amy Logan with any questions.
A Quick Look into Two Worlds: Video Games and GIS By Wael Alhaj
Imagine you’re playing your favorite video game, exploring new territories, or maybe you’re looking at a map, trying to find a place you’ve never been. Sounds pretty different, right? Actually, not as much as you might think! Video games and Geographic Information Systems (GIS), another term for map-making and analyzing, share more in common than you’d guess. Video games are all about fun and adventures, while GIS sounds like serious business with maps and data. But if we look more in depth, they are close related in the world of technology.
Both video games and GIS are big on creating spaces, whether it’s a fantasy land in a game or a detailed map of your city. In video games, you might roam around imaginary places or ones that look similar to the real life. GIS, on the other hand, is more about mapping out the real world, but sometimes it uses simple and easy to understand pictures instead of super detailed ones. Both are all about giving you a sense of space one for fun, the other for facts and figures.
Making Things Look Real
As game players we ask, how do some games look almost like real life? This is called “visual realism” and it’s pretty impressive in today’s games. GIS does something similar, but instead of creating life-like world and landscapes, it shows real-life information in a way that makes sense by converting the data into a colorful map. Games go for the impressive appeal and eye-catching goal with graphics, while GIS tries to make complex info easy to get.
Handling Loads of Data
Video games and GIS deal with a lot of details. Games keep track of everything in their world such as places, objects, characters. As Same as in GIS, which combines location and spatial info with all sorts of other data. They both handle a ton of different kind of information, showing us how to manage and use big sort of data in different ways.
Scripts and User-Friendly Features
Both video games and GIS use some smart tricks behind the scenes. They’ve got algorithms for figuring out space related stuff, like how to find the best path from “A” to “B”. Games focus more on making everything interactive and fun, with everything happening in real-time. GIS concept is more about analyzing space and showing data in a fixed way. But deep down, the theories, codes and scripts they use is pretty similar.
Challenges and Possibilities
Video games and GIS can learn a lot from each other. Games are always pushing the limits of making things look real and keeping players engaged and hooked, which could be great for GIS to make maps more interesting and interactive. On the flip side, GIS focus on getting every detail right and accurate could help games, especially when a developer wants a game to mimic the real world.
So, the intersection where video games and GIS meet shows us how two areas we thought were worlds apart can actually help each other out. As tech keeps evolving, we’ll probably see more of this mix and match, leading to even great results in both gaming and the map-making industry. It’s all about being creative with space, whether it’s for fun, learning, or visualize facts and information.

For all the reasons mentioned above, GIS industry, including companies like ESRI, is actively working on developing various plugins and tools for game engines such as Unity and Unreal Engine. These tools are designed to help game developers and designers to create realistic world maps and 3D content using GIS data. For further reference, you can explore these links: ArcGIS for Unity (https://developers.arcgis.com/unity/) and ArcGIS for Unreal Engine (https://developers.arcgis.com/unreal-engine/). Additionally, the paper “Videogames: the new GIS?” by Ifan D H Shepherd & Iestyn Bleasdale-Shepherd (https://www.researchgate.net/publication/228577009_Videogames_the_new_GIS), offers valuable insights and is a great resource while exploring this topic.
The Iowa Geographic Map Server is a gem of historical and contemporary statewide aerial imagery for Iowa from the 1930s to 2021. It also has many other statewide layers including:
elevation maps (LiDAR and USGS topographic maps),
historical maps (General Land Office survey maps from 1800s, Andreas Atlas, historic topography),
land cover maps (historical and contemporary)
geology (landforms and bedrock)
Here’s your challenge: Zoom into your city or a place of significance to you and discover how it has changed over the years, look at how the land cover changed, challenge yourself to find as many changes as you can.
OpenStreetMap (OSM) is a publicly created and maintained map of the world – the Wikipedia for maps. Anyone with access to an internet browser can view the map and can sign up for a free OpenStreetMap account to edit and update the map. Edits to the map are reviewed and validated by other members of the community. If you are new to OpenStreetMap, visit their welcome page to a short introduction: https://osmgeoweek.org/guides/intro.
Here are several ways to get engaged with OpenStreetMap:
~ Review your local OSM basemap for accuracy and consider adding community features that are missing or need updating.
~ Spend time working on a Humanitarian OpenStreetMap project. For a current list of priority project visit: https://tasks.hotosm.org/explore
~ Only have a little bit of time? Consider MapRoulette, the game of mini mapping challenges, it breaks OSM work into snack-sized “challenges.” Earn points by fixing validation issues, turning nodes into areas, adding missing tags, and through countless other little tasks that contribute to a healthier map.
